P And I would/coul get involved tangentially- for those who/travel move from a permissive to a restrictive state-

Corfield v Coryell suggests we have a right to, and FULL USE OF, the property we own. So moving from one state where you can have a Colt AR-15 model LE6920 for example, to a state where you can't- would/could bring P And I into play, but the driving force would still be (Dormant) Interstate Commerce, as most of those state laws prohibit the importation of such firearms, which like all commerce does not require a transaction.
